browse graphicPaleoclimatology - Paleoceanography
This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Paleoceanography. The data include parameters of paleoceanography with a geographic location of North Pacific Ocean. The time period coverage is from 139000 to 880 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.

Supplemental Information
ABSTRACT SUPPLIED BY ORIGINATOR: Sedimentary accumulation of biogenic components (organic carbon, opal, and biogenic barium) on the northwestern Mexican margin declined during every glacial interval of the past 140 kyr, indicating decreases in upwelling-induced productivity during cold periods. The glacial-interglacial contrasts in upwelling on this margin are attributed to reversals in land-ocean thermal contrast, the waxing and waning of the Laurentide Ice Sheet, and consequent responses of the western hemisphere wind fields. This scenario is consistent with three independent lines of evidence: terrestrial paleoclimatic data, general circulation model results, and our marine records. This pattern of glacial-interglacial variability in upwelling off NW Mexico is opposite to that observed in other low-latitude and midlatitude upwelling areas, such as the eastern equatorial Pacific. These results add to a growing pool of observations that the response of oceanic upwelling to glacial climatic forcing has been regionally variable.
PurposeRecords of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations.
